6-3 A basic experiment of detecting a camera position using a rewind wire

Abstract

The 3-dimensional position data of the camera is necessary in the virtual studio, compositing CG images. Therefore we fixed one end of the wire to the camera and another end of to the constant tension spring, had fundamental experiment. If we set tension in 230gf, the cameraman move freely without feeling it as load, and was able to detect the position within mm order.
